This application is a continuation of U.S. patent application Ser. No. 15/335,379 filed on Oct. 26, 2016, the entire disclosure of which is incorporated herein by reference.

FIELD

This disclosure relates generally to protective cases for computing devices and more particularly, protective cases for computing devices such as, tablets, laptops, and smart phones.

BACKGROUND

With increasing regularity, protective cases are being constructed for a variety of computing devices such as smart phones, tablets, laptops, and/or other portable computing devices. Their respective designs vary, ranging between degrees of protection as well as facilitating use of the computing device in a more protected environment.

Cases have been known to be constructed from molding using silicon or thermoplastic polyurethane rubber that provides some basic protection against drops and scratches. Other case designs have been constructed from relatively stiffer injected plastics such as polycarbonate.

The design and construction of the known cases therefore vary depending on the desired amount of protection, costs, and consideration for certain materials and mounting schemes balanced with features that facilitate performance of the computing device itself. For example, certain material may provide basic structural protection, be relatively cheap, but this material may induce too much friction (e.g. grip) to the user that interferes with easy attachment of the case with the device or grip with other articles such as parts of the user's body or other objects foreign to the case.

In addition to material selection, cases can suffer from being too bulky and difficult to stow away. It is also known that materials for certain cases can degrade over time thereby diminishing protective capabilities of the case as well as loosening its attachment with the computing device. Aesthetically, a worn case also diminishes the overall impression of the case and the attached computing device. Such cases can also have reduced bulk versus their rubber counterparts. Plastic injected mold cases can suffer from passing on relatively high material stresses to the computing device itself due to the differing elasticity and cushioning. For computing devices with sensitive displays or input devices, such protective devices may therefore may not be desirous. Certain cases also decrease the ability of a device positioned within them to expel heat by virtue of the materials chosen or the coverage over vents or other heated areas of the device.

Certain hybrid combinations have therefore been designed to combine each approach with the softer, cushion portions being placed in communication with the computing device whereas the exterior portion being constructed from the less bulky, injected plastic.

Yet, even with these hybrid solutions, stress tests to the computing devices caused by normal use through drops or collisions can lead to device damage and case separation. In turn, the user may have to fix the device, buy a new one, and/or re-assemble the case with the computing device. Furthermore, many cases fail to completely protect or envelope the associated computing device which unnecessarily risks structural harm to the computing device. Therefore, a need exists to resolve these and other problems in the art.

SUMMARY

The following simplified summary is provided in order to provide a basic understanding of some aspects of the claimed subject matter. This summary is not an extensive overview, and is not intended to identify key/critical elements or to delineate the scope of the claimed subject matter. Its purpose is to present some concepts in a simplified form as a prelude to the more detailed description that is presented later.

In some embodiments, a composite case for a computing device is disclosed having a first portion and second portion. The first portion is operable to protect and detachably connect to a display portion of the computing device, the first portion having one or more perimetral fasteners disposed on edges of the first portion. The second portion is operable to protect and detachably connect to an input device portion of the computing device. The second portion may have one or more perimetral fasteners disposed on edges of the second portion. The display and input device portions may be detachably connected to each other through a multi-pivot hinge unit. The multi-pivot hinge unit may be operable to rotate about one or more computing device axes defined between the display and input device portions to move the computing device between open and closed states. A hinge cover portion can be connected to the first portion to detachably receive and surround the multi-pivot hinge of the computing device. A protective shell may be formed between the first and second portions when the first and second portions are joined at the hinge cover portion. One or more perimetral fasteners of the first and second portions opposite the hinge cover portion can be secured with each other in a closed position.

In certain embodiments, the first portion includes a resilient portion dimensioned to detachably receive perimetral edges of the display portion and a rigid portion detachably connected to a rear surface of the display portion of the computing device, the rigid portion being impact resistant and dimensioned to shield the rear surface of the display portion. In certain embodiments, one or more impact resistant corners are formed with the perimetral edge and/or the rear surface.

Also in certain embodiments, the hinge cover portion can include an elongate hemispheric chamber for receiving the hinge cover of the computing device. A series of elongated channels can be extended along the chamber between lateral edges of the second portion. A plurality of fastener tabs can be extended from a lower edge of the chamber to upper and lower surfaces of the second portion. The second portion can be substantially rigid and the hinge cover can be resilient. The second portion can include a plurality of receivers spaced a predetermined distance apart and formed from cutouts of the second portion along a rear edge of the second portion. The cutouts associated with the receivers of the second portion can render flexible the rear edge of the second portion.

In other embodiments, the hinge cover portion can include a rigid elongate hemispheric chamber extended between lateral edges of the second portion of the case. The rigid elongate hemispheric chamber can be axially aligned with and receive the hinge cover of the computing device. A gap may be provided for moving between open and closed states between the multi-pivot hinge of the computing device and the chamber when the hinge cover portion is secured to the multi-pivot hinge. The gap may depend on the amount of rotation desired between opened and closed states, number, size, and/or shape of hinges of the multi-pivot hinge unit. A resilient fastener tab can be extended from a lower portion of the chamber for connecting the hinge cover portion to a recess on a lower surface of the second portion of the case. The tab can be extended between opposite lateral edges of the second portion and may be substantially planar to the recess on the lower surface of the second portion. The resilient fastener tab can include a first portion substantially surrounding an outer surface of the chamber and a second portion pivotally attached to the first portion along an edge axially aligned with the chamber. The second portion can be operable to be substantially planar and connected to the recess of the second portion of the case. The first and second portion of the tab can be formed from a shared outer grip inducing surface.

In some embodiments, a retention band can be extended from opposite ends of the chamber of the hinge cover portion. The retention band can be operable to securely retain the multi-pivot hinge of the computing device with the chamber. The retention band can be movable and/or flexible (e.g. be an elastic bungee, a band such as an elastic, an adjustable strap, a band containing linked or hinged subunits or portions, etc.). The hinge cover portion can include a plurality of bulkheads or structural members normal to the longitudinal axis of the rigid hemispheric chamber and extended along the chamber between lateral edges of the second portion. The second portion can be substantially rigid and the hinge cover can be substantially resilient. The recess of the second portion can render flexible the rear edge of the second portion.

In other embodiments, the hinge cover portion may be formed from multiple individual pieces and the retention band can be attached to both sides of portions of the case or attached onto either or both sides of the case or the hinge unit of the computing device.

In some embodiments, the perimetral fasteners of the first portion can include a forward edge fastener defined by an inwardly facing lip operable to detachably secure to an upper edge of the display portion opposite the hinge cover portion. A plurality of lateral edge fastener tabs can also be included that extend downward from opposing lateral edges of the first portion, each lateral edge fastener tab being operable to flex outwardly and securely engage with a corresponding receiver disposed on a lateral edge of the second portion. The corresponding receiver of the second portion can extend outwardly from the respective lateral edge of the second portion and may be capable of being received by a recess of the corresponding lateral edge fastener tab of the first portion. The lateral edge fastener tab can be resilient and the corresponding receiver of the second portion can be rigid. An axis of rotation of the hinge cover portion can be co-extensive to a hinge axis of the multi-pivot hinge unit. In certain embodiments, the multi-pivot hinge unit is an armadillo hinge assembly. Additionally, the first portion can provide impact resistance to the display portion regardless of whether the second portion is detachably connected to the input device portion or the first portion (e.g, if the display portion is a tablet and is not connected to the hinge of the computing device, the first portion, or the input device portion). Accordingly, the first and second portions may not be directly attached at all, they may be directly attached irrespective of whether input and display portions are connected, or the first and second portions may be attached to the other when the input device and display portions are connected via the multi-pivot hinge unit.

The first portion can include one or a plurality of impact resistant portions or resilient portions. Perimetral edges of the first portion can extend away from a rear support surface and terminate in a flexible inwardly extending lip operable to flex outwards and securely retain the display portion of the computing device. The lip can be thicker than the portion of the perimetral edge extending away from the rear support surface.

In other embodiments, a method of protecting a computing device is disclosed. The computing device can have a display portion and an input device portion detachably and pivotally connected through a multi-pivot hinge unit operable to rotate about one or more computing device axes defined between the display and input device portions to move the computing device between open and closed states. The method can include: attaching a leading edge and/or lateral edges of the display portion with one or more perimetral fasteners a first portion of a composite case; the first portion comprising a substantially rigid rear surface and resilient perimetral edges; aligning the display portion planar with the rear surface of the first portion of the composite case; attaching edges of the input device portion with one or more perimetral fasteners of a second portion of the composite case, the second portion comprising a substantially rigid rear surface: aligning the input device portion planar with a rear surface of the second portion; and positioning the multi-pivot hinge unit in a hinge cover portion of the composite case, the hinge cover portion having a rigid elongate hemispheric chamber in which the multi-pivot hinge is movable between opened and closed positions, the hinge cover portion being connected to a rear edge of the first portion of the composite case.

The method may also include forming a protective shell about the computing device between the first and second portions when the first and second portions are joined at the hinge cover portion and one or more of perimetral fasteners of the first and second portions opposite the hinge cover portion are secured with each other in a closed position.

The method can also include positioning the hinge cover of the computing device within an elongate hemispheric chamber the hinge cover portion, the hinge cover portion including a series of elongated channels extended along the chamber between lateral edges of the second portion; and a plurality of fastener tabs extended from a lower edge of the chamber to upper and lower surfaces of the second portion; the second portion being substantially rigid and the hinge cover being substantially resilient.

The method can also include positioning the hinge cover of the computing device within a rigid elongate hemispheric chamber extended between lateral edges of the second portion of the case, the rigid elongate hemispheric chamber being operably to axially align with and to receive the hinge cover of the computing device, the hinge cover portion comprising: a gap for moving between open and closed states between the multi-pivot hinge of the computing device and the chamber when the hinge cover portion is secured to the multi-pivot hinge; a resilient fastener tab extended from a lower portion of the chamber for connecting the hinge cover portion to a recess on a lower surface of the second portion of the case, the tab extended between opposite lateral edges of the second portion and being substantially planar to the recess on the lower surface of the second portion.

A variety of methods and systems of utilizing and assembling the disclosed case is also contemplated in a variety of situations and environments. To the accomplishment of the foregoing and related ends, certain illustrative aspects are described herein in connection with the following description and the annexed drawings. These aspects are indicative, however, of but a few of the various ways in which the principles of the claimed subject matter may be employed and the claimed subject matter is intended to include all such aspects and their equivalents.

 DETAILED DESCRIPTION

The features of the presently disclosed solution may be economically molded or assembled by using one or more distinct parts and associated components which, may be assembled together for removable or integral application with a known or to-be-designed computing device case in an economical manner, wherein the features of the present disclosure may form the herein disclosed servicing apparatus regardless of the particular form. Unless defined otherwise, all terms of art, notations and other scientific terms or terminology used herein have the same meaning as is commonly understood by one of ordinary skill in the art to which this disclosure belongs.

Terms with commonly understood meanings may be defined herein for clarity and/or for ready reference, and the inclusion of such definitions herein should not necessarily be construed to represent a substantial difference over what is generally understood in the art. All patents, applications, published applications and other publications referred to herein are incorporated by reference in their entirety. If a definition set forth in this section is contrary to or otherwise inconsistent with a definition set forth in the patents, application, published applications and other publications that are herein incorporated by reference, the definition set forth in this section prevails over the definition that is incorporated herein by reference.

As used herein, “a” or “an” means “at least one” or “one or more.” As used herein, the term “user”, “subject”, “end-user” or the like is not limited to a specific entity or person. For example, the term “user” may refer to a person who uses the systems and methods described herein, and frequently may be a technician. However, this term is not limited to end users or technicians and thus encompasses a variety of persons who can use the disclosed systems and methods.

The disclosed solution can now be better understood turning to the following detailed description. It is to be expressly understood that the illustrated embodiments are set forth as examples and not by way of limitations on the embodiments as ultimately defined in the claims. An embodiment in accordance with the present disclosure provides a cover for a computing device such as a laptop, a tablet or any other portable computing device. The cover can be made of multiple parts, integrally formed therewith or detachable.

It is understood that “computing device” can mean any computer such as a laptop, a tablet computing device, a mobile device such as a cellular phone, a mobile phone, a smart phone, or the like.

“Shield” as used herein with the disclosed case can mean to protect, wrap around, or envelope a corresponding computing device in a manner that conceals the computing device from injuries during a drop or accident such as by impact or collision.

“Impact resistant” or “impact resistance” as it relates to the herein disclosed case features can mean any feature designed to withstand relatively high applied forces or related shock. Accordingly, features or materials described herein as providing impact resistance or being impact resistant utilize material properties and/or structural design of the case directed towards mitigating the effects of expected events in the life-cycle of the case and corresponding computing device that incur impact (e.g. drops, collisions, accidents, etc).

The herein disclosed solution described a case capable of exhibiting the shock resistant benefits of a case with elastomeric edges or outer portions combined with the consumer usability benefits of a resilient outer case such as relatively stronger plastics. The herein described solution may also be a composite case with some combination of one or more elastic materials with one or more harder, resilient materials, such as injection molded plastic and/or rubber, in a way that forms a permanent bond therebetween resulting in a protective system that sufficiently securely retains and protects a computing device in most operating conditions including, but not limited to, the standards set forth by MIL-STD 810G, 506.6 VI. The herein disclosed solution also contemplates a composite case in which the geometric shape of the constituent components maximizes overall structural strength and impact resistance while minimizing material weight and size.

For simplicity and illustration purposes only, the presently disclosed cases 10, 110 are depicted for use with a laptop and/or tablet device though the solution is not so limited and could be used with other referenced computing devices as understood in the context of this disclosure and other numerous consumer electronic devices, wherein cases 10, 110 would employ similar details, features and benefits.

The herein disclosed case offers solutions to protect and shield computing devices employing multi-axis or multi-pivot hinges to rotatably secure input and display portions of said computing device. It is understood that multi-axis or multi-pivot hinges can incorporate a plurality of discrete hinge units, with respective rotational axes, and can move between a plurality of opened and closed positions. In certain embodiments, some or all of the discrete hinges of the multi-pivot hinge unit can include a rotational limiter to limit degree of rotation of the respective hinge relative to an adjoining discrete hinge.

Turning to the figures, FIGS. 1-4 show forward and rear perspective views of the herein disclosed case 10 assembled with an exemplary computing device 50. Computing device 50 includes an input portion 54 (e.g. a keyboard) and a display portion 58. Portions 54 and 58 may be detachably interconnected through a multi-pivot hinge 59. Preferably, hinge 59 is disposed at the trailing edge of portion 54 and is an armadillo hinge assembly. Multi-pivot hinges that can be used with device 50 are designed to rotatably secure separate portions of device 50, such as input 54 and display 58 portions.

FIG. 1 specifically depicts a perspective view of a case 10 assembled with computing device 50 in an opened state. FIG. 2 depicts a similar embodiment but instead case 10 is now in the process of being collapsed to form a shield around computing device 50 as discussed more particularly below. FIG. 3 depicts a forward perspective view of case 10 assembled with device 50 in an opened state, wherein portions 54 and 58 can be seen assembled with the other through hinge 59. FIG. 4 depicts case 10 and device 50 of FIG. 3 but in an exploded state, wherein portions 58 and 30 are assembled with each other but are exploded from hinge 59. Case 10 may be operable to securely retain and shield computing device 50 and preferably may be constructed from a base portion 20 and an upright portion 30. Portion 20 may be designed to receive and shield an input device 54 whereas portion 30 may be designed to receive and shield display portion 58.

Portion 20 may also include a hinge cover portion 40 attached to a trailing edge of base portion 20. Portion 40 may be designed to receive hinge 59 of device 50 when device 50 is in an assembled state (portions 54 and 58 connected to each other across hinge 59) or when portions 54 and 58 are mechanically disconnected from the other.

Portion 30 may be constructed from a relatively resilient material along its perimetral edge portion 32. Edge portion 32 may be substantially or partially flexible in one or more predetermined areas. For example certain areas of portion 32 immediately adjacent or nearby corners 34 may be relatively resilient or stiff whereas areas 33 disposed in a central portion closer away from corners 34 may be more rigid so that portion 32 can conform to portion 58 as needed. Corners 34 in turn may be reinforced with one or more impact resistant materials and/or designs to withstand and shield portion 58 and device 50 during collision, drop or otherwise accidental conduct. Notably, when portion 30 is engaged with display portion 58, in certain embodiments it provides impact resistance to display portion 58 regardless of whether display portion is engaged with input portion 54. For example, display portion 58 may be removed and used as a tablet apart from the input portion 54, while it maintains impact resistance while it is engaged with portion 30. Often, both portions 54, 58 maintain impact resistance as portions 20 and 30 remain engaged with them even as the device is used in a tablet mode. Opposite corners 34 on the lower, trailing edge may be one or more perimetral fasteners 31 disposed on edge 32. Fasteners 31 may be operable to flex and securely engage with corresponding perimetral edge portions of portion 58.

Stylus receiver 37 may also be disposed on an upper edge of portion 30. Receiver 37 may be designed to receive stylus 55. Stylus 55 may be a digital stylus in the shape of an elongate member such as a pencil or pen. In this respect, receiver 37 is shown as substantially cylindrical with flexible, separate lips operable to slidably receive and retain mechanism 55. However, receiver 37 may be in any shape or manner including a two-part bendable, flexible receiver operable to securely engage any other control mechanism of device 50 including a mouse, remote control, or the like. Receiver 37 may also be integrally formed with edge 32 or detachable therewith as needed or desired.

Preferably, edge 32 may be defined by extending substantially normal away from the rear support surface 33 and terminating in an inwardly extending lip. The Hp may be wider or thicker than the lower portion of edge 32 extending away from the rear support surface 33. In this respect, perimetral edge 32 may be operable to flex outwards when receiving portion 58 while also being capable of securely retaining device 58 once assembled under the described lip and edge 32.

Portion 30 may also include optional optical system cutout 31 and/or actuator surfaces or cutouts positioned with edge 32. Cutout 31 may be formed by being trimmed or cut from edge 32 by the end-user according to particular device 50. Edge 32 in turn may be formed with pre-etched portions operable to be trimmed or modified as needed by the end-user. Cutout 21 may also include corresponding hingeable covering surfaces or detachable covers that can be easily moved as needed or required to further shield corresponding optical system 56 of device 50 and/or related actuators positioned along the corresponding perimeter of device 50. In this regard, portion 30 is a composite portion that advantageously includes a hybrid rigid rear surface 33 in combination with resilient protection of edges 32 to portion 58 across a range of operating environments.

Portion 20 may be constructed from substantially rigid material. Portion 20 may include a perimetral edge 22. Portion 20 may include a plurality of corners 34 with reinforced material for protecting corners of portion 54. Edge 22 may extend substantially normal away from the rear support surface 23 and terminating in an inwardly extending lip. The lip may be discontinuous along lateral edges and the leading edge so as to permit flexing of the rigid portion 20 as well securely fasten with corresponding fasteners of portion 30 in a closed position. For example, the leading edge 27 of portion 20 may include a recessed lip that is lower than the remaining lip of edge 22. This is particularly advantageous in inducing a predetermined flex of case 10 when assembling with portion 54 while also maintaining a rigid outer shell of 20 for portion 54 across a plurality of operating environments. Some or all of lateral edges of edge 22 may also be recessed or completely removed adjacent the trailing edge of portion 20. In this respect, perimetral edge 22 may be operable to flex outwards when receiving portion 54 while also being capable of securely retaining device 54 once assembled under the described lip and edge 22. Lip of edge 22 may be wider or thicker than the lower portion of edge 22 extending away from the rear support surface 23.

One or more lateral fastener tabs 36 may be positioned along edge 32 for releasable attachment with corresponding edge 22 of portion 20. Tabs 36 may be constructed from substantially resilient material capable of flexing. Tab 36 may also include a receiver for fastening with corresponding fastener 26 of portion. However, tab 36 is not so limited and instead may include an outward extending fastener capable of securely engaging with tab 26 and/or edge 22 of portion 20.

Turning to FIG. 5, case 10 is depicted in a closed state so that rear support surface 33 can be readily observed. Surface 33 may be defined by a structural backing plate and be structurally reinforced by one or more upraised portions defined by thicker material relative to non-upraised portions disposed adjacent thereto. Advantageously, the upraised portions with the less thick portions of surface 33 may provide additional rigidity, strength or stiffness to portion 30 of case 10 in a manner that optimizes overall case 10 weight and material costs. FIG. 5 also depicts portions 30 and 20 assembled to each other so that tabs 36 are securely engaged with corresponding fasteners 26.

FIG. 6 depicts a similar view of FIG. 5, wherein case 10 has been rotated to observe portion 40. As can be seen, portion 40 extends between the lateral edges 22 and 32 of portions 20 and 30, respectively. Portion 40 can attach to the trailing edge of portion 20 whereas portions 20 and 30 are connected to each other through hinge 59. In other words, in certain embodiments, portion 20 may be the only feature of case directly attached to portion 40 while portion 30 is loosely assembled therewith only through hinge 59. It is to be understood that case 10 is not so limited, however, and portions 20 and 30 may both directly attach to portion 40.

FIG. 7 depicts a side plan view of the case 10 and device 50 of FIGS. 5-6. As shown, portion 40 can completely receive hinge 59. Portion 40 may include one or more lower fasteners 42 that fasten to the trailing edge of portion 20. Fasteners 42 may be planar and/or parallel with surface 23. Portion 40 may also include an elongate hinge receiving chamber defined by an elongate contoured extruded surface 44. Surface 44 may be substantially hemispherical with one or more grooves or channels of varying thickness. In this regard, surface 44 may be thicker than corresponding fasteners 42 and more resistant to bending. However, thinned out grooves or channels of surface 44 may permit the chamber defined by surface 44 to bend or conform with hinge 59 as hinge 59 rotates between opened and closed positions.

FIG. 8 depicts a side plan view of the device of FIG. 7 in an opened position, wherein portions 20, 30, and 40 are assembled with each other. As shown, a gap can be included in between an inner surface of portion 40 and hinge 59 that permits hinge 59 to rotate between opened and closed positions. As also shown, portion 30 may not directly attached to portion 20 but instead may be assembled therewith indirectly through hinge 59 being directly connected to portions 54 and 58 (each of which may be directly attached to or separate from respective portions 20 and 30).

FIG. 9 depicts a top plan view of case 10. As shown, portion 40 is assembled with portion 20 which is positioned underneath portion 30 in this embodiment. FIG. 10 depicts a bottom plan view of the case 10 in FIG. 9, wherein a plurality of fasteners 42 can be seen fastened to portion 20 along its trailing edge 25. The attachment area of portion 40 associated with 42 may be completely removed or thinned out which renders portion 20 capable of additional flexing or twisting. Fasteners 42 may be separated by one or more spaces 28 along the trailing edge.

FIG. 11 is a close-up forward perspective view of section A of FIG. 10 and FIG. 12 is a close-up rear perspective view of section A of FIG. 10. As can be seen, at trailing edge 25 of portion 20 a recess or cutout has been positioned to receive fastener 42. In some embodiments, fastener 42 may be fastened only to the outer surface of portion 20, only the inner surface of portion 20, or both the inner and outer surfaces of portion 20. As can be seen, surface 44 can include a plurality of grooves or channels of varying thickness that collectively form a chamber for receiving hinge 59.

FIG. 13 is a forward perspective view of another embodiment of the protective case 110 for computing device 50. It is to be understood that features of case 110 with the same reference numerals as case 10 are intended to carry substantially similar function and structure as those previously described in case 10. However, portion 40 differs from portion 140 as discussed more particularly below. FIG. 14 is rear perspective view of case 110 and device 50 shown in FIG. 13. As shown in FIG. 14, portion 140 includes a fastener 142 that extends from surface 144 and attaches to trailing edge 125 of portion 30. Portion 120 in this respect does not include spaces 28. Instead, edge 125 may include a recessed portion that forms a flange onto which fastener 142 may be fastened. Fastener 142 may be a Wabash hinge formed from a plurality of or a single unitary surface that extends between lateral edges 122 or may be constructed from a plurality of separate layers or laminates. In one embodiment, an outer layer of fastener 142 may be grip inducing for enhanced handling by user and stability of case 110 and device 50 when seated and assembled onto a surface for use.
